v?Pow2o3

Raises each element of a vector to the constant power 2/3.

Syntax

Fortran:

call vspow2o3( n, a, y )

call vmspow2o3( n, a, y, mode )

call vdpow2o3( n, a, y )

call vmdpow2o3( n, a, y, mode )

vsPow2o3( n, a, y );

vmsPow2o3( n, a, y, mode );

vdPow2o3( n, a, y );

vmdPow2o3( n, a, y, mode );
